 Trustindex verifies that the original source of the review is Google. I didn't use them this year but they are the best roofers in town both customer experience, professionalism and quality workmanship. Your name is everything and at every part of the sales process to installation this company is great to work with and deal with. Even with the most demanding of customers such as myself I know they do a great job. I have used them in 2023 for one of my properties and wish I used them again this year but  it was too late in the year and as of today it's snowing. I was still able to get the job done but they are better to deal with.

 Trustindex verifies that the original source of the review is Google. I've had Strasser & Lang for a few different home projects now. The employees skill, attention to detail, and ability to make things look great while maintaining proper functionality is what I've appreciated most. They are in and out with no mess, and just a bunch of nice people overall. Highly recommend for any type of exterior work.
